| dc.description.abstract | We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, K2-131b, was discovered in K2 Campaign 10. It has a radius of 1.81<SUB>-0.12</SUB><SUP>+0.16</SUP> R<SUB>\oplus</SUB> and orbits a G dwarf with a period of 8.9 hr. Radial velocities obtained with Magellan/PFS and TNG/HARPS-N show evidence for stellar activity along with orbital motion. We determined the planetary mass using two different methods: (1) the "floating chunk offset" method, based only on changes in velocity observed on the same night; and (2) a Gaussian process regression based on both the radial velocity and photometric time series. The results are consistent and lead to a mass measurement of 6.5± 1.6 M<SUB>\oplus</SUB> and a mean density of 6.0<SUB>-2.7</SUB><SUP>+3.0</SUP> g cm<SUP>-3</SUP>. | en_US |
